Now, in the world will be generated new packed ores which will have more resources. You can get them using only iron pickaxe, but you will need not to put them in the furnace. For example, if you break packed iron ore, you will get 3 iron ingots immediately!

Was added solid dirt.
Added solid ore. Now, under ground will be generating solid ore. It is simple stone (with another texture). It will take more time to destroy this new rock.
